the EPIDEMIOLOGIST'S role in organizing CENSUS: Did epidemiologist play a census?

A national census is a systematic process of collecting information on a population (population census, health census, national survey, disease case census, etc.).Epidemiologists play a vital role in the planning, methodological rigour and analysis of the data collected, particularly when the survey concerns public health issues.They use data from a country's population survey - usually obtained through a census - to study the frequency, distribution and factors associated with diseases within that population.As such, the epidemiologist is a key player in the national census, as they help to ensure the scientific quality of the process, from the design of data collection tools through to the analysis, interpretation and use of the results to inform public health decisions.
